Recently-promoted Joe Savery won his second start for Lehigh Valley (AAA), improving to 2-0, with a 2.45 ERA, at that level. Don't get overly excited by those gaudy stats. A Small Sample Size Alert is necessary when looking at any numbers, here, as the rest of the stats indicate that Savery hasn't been very effective. Savery has allowed ten hits and nine walks (five whiffs), in his eleven AAA innings. He has had more than his fair share of BABIP, and LOB%, luck.
Savery could be competing for a spot in the rotation next year- with Lehigh Valley. He needs to significantly improve his command, if he wants to escape AAA.

Gustavo Chacin improved to 6-2, with a 3.26 ERA, in his last three starts for Lehigh Valley. Chacin also has a 4.22 FIP. He has no future with the Phillies' organization. I wonder if any organization would trade something (a low-A prospect?) for Chacin? Either way, Chacin likely won't be back in 2010.

Michael Taylor has 83 ABs at AAA, posting a .727 OPS, including 3 HRs. Not a bad start. He could be brought up to the parent Phillies in September, with a postseason spot possible, if things go well.

At Reading (AA), OF Jeremy Slayden announced his retirement, with OF Steve Susdorf promoted from Clearwater (A), to take Slayden's roster spot. The 27-year-old Slayden played at AAA this season, struggling to post a .229/.295/.398 line. Not enough for the left-handed hitting outfielder to be a viable prospect.
The 23-year-old Susdorf excelled with Clearwater, slugging his way to a .373/.423/.513 line. The left-handed hitting Susdorf needs to work on his defensive game, but could find himself in AAA for 2010.

Tyson Brummett has been placed on the Reading DL, with right elbow inflammation. B.J. Rosenberg was promoted from Lakewood (low-A). Brummett has not been very effective this season, pitching in both AA and AAA. The results could have been caused by injury, or this could just be a convenient way to get Brummett off the roster for awhile. Either way, Brummett is more minor league filler, than prospect.
Rosenberg was outstanding at Lakewood: .89 ERA, 11.68 K/9, 6.5 K/BB, 1.33 FIP. Rosenberg will be 24 in September, so AA is a bit more of an age-appropriate level. A strong finish to 2009 with Reading, and Rosenberg could be in AAA for 2010.
(Was surprised to see Rosenberg promoted to AA, before Clearwater's Michael Schwimer, but Schwimer could be up with R-Phils, before long.)

Reading ace Kyle Drabek had a poor start at Binghamton on Saturday night, allowing four runs in five innings (six hits, four walks/four whiffs).
Drabek was making only his third road start, despite making twelve appearances for the R-Phils. He continues to struggle against left-handed batters, who are hitting .333 against the 21-year-old southpaw. Drabek threw thirty-two innings in 2008, after coming off TJ surgery, and has thrown one-hundred forty (at two levels), this season. That is a rather large jump, especially for a young pitcher coming off surgery. It might be time to start limiting Drabek's innings/pitches.

Reading northpaw Vance Worley has posted a 7.89 ERA, in his last ten starts. Worley has surrendered seventy-six hits, and eighteen walks (thirty whiffs), in his last fifty-one innings. The twenty-one year old threw sixty-nine innings in 2008, and is up to one-hundred and twenty-six innings, this season. Another large innings jump, and Worley's innings might also need to be limited, as the season progresses.
Yohan Flande, Reading's 23-year-old southpaw, has pitched well recently. But his innings (53 in 2008, 124 in 2009) are also getting a bit high...

Clearwater (A) has seen their roster depleted by callups. Not sure if the Threshers have any worthwhile position prospects at this point, with DomOnic Brown, Steve Susdorf, and Tim Kennelly all having been promoted to AA.
But there are still a number of pitching prospects to watch, including Michael Schwimer, Joe Bisenius, Darren Byrd, Tyler Cloyd, Drew Naylor, and Jon Velazquez.
